Finally changed out my 02 yesterday. This is a great method for doing so, but I must say one thing: You must have some real tiny hands to fit past that wiring harness!!! I could barely get my hand half way past it (while really pushing it out of the way). Painful, but you gotta do what you gotta do. Got my hand far enough in to hand tighten the O2, which was a huge help. If you cant get your hand on it, it would take a while.
Total time: 1 hour. Not too bad at all.
